Application filed Kay 3, 1906'. Serial No. 315,015.

To all whmn it mo/y concern:

' Belt known that we, DAVID C. Firms and (Jmvau Q. Pa'r'rsnson, citizens of t, e United States :of America, residin at Union't'o'wn, in thecounty of Fayettem l State of Pennsylvania, have'invented certain new and useful Improvementsin Indicators of which the following is a specification, reierence being had therein to the accompanying drawing.

This invention relates to certain new and useful improvements in indicators, and more particularl tothat type of indicator adapted to be ectric'all actuated in connectlon with street and mi wafy cars.

Ou'r invention has or its-primary object. the revision of novel means for indicating the different streets and stations which a car approaches, said meansbeing automatically controlled and actuatedby the car passing predetermined points along the entire route this end, we have devised an indicator for displaying thename of each street or station a car approaches, and in connection with the indicator, we have also devised a novel advertisin' medium, which displays a plurality of a vertisements, an advertisement being displayed each time the indicator "is actuated. i

- The present invention is an improvement upon our street car indicator, No. 813,144, patented February 20th, 1906, and in the present invention we employ'a portion of the indicator mechanism set forth in the abovementioned application, together with certain novel improvement which form the. sub'ect matter 0 this up ligation.

ith theabove and otl ier objects in view, which will more readily appear as the nature of the invention is better nnderstood, the same consists in the novel construction, com-- bination and arrangement of arts to behereinafter more full describ and claimed, and referring tov t e drawing accompanying this application, like numerals 'of reference designate corresponding parts throughout the several views, in which Figure 1 is a frontelevation of our improved indicator, Fig. 2 is a vertical sectional view of the indicator casing, Fig. 3 is a fragments vertical sectional view of a street car e nipped with our improved indicator, Fig. is a vertical sectional view of a the street car illustrating the inicator in side elevation, Fig. 5 is a pers ec- Bl tiveview of one of the plate holders use in connection'with the indicatorgFig. 6 is a- ,being locate -'wall 6 of the casing.

In the accompanying drawings, we have illustrated a conventional form of street clt'r l-,-which.is electrically operated, a trolley pole 2 and trolley wire 3-, together with other mechanism (not shown) being employed for this purpose. p

Ou'r ihvention resides in an indicator 4, which is preferably mounted in the forward end of the car 1', whereby it may be easily observed by the occupants of the ca,r. The indicator comprises a casing 5 having a slotted front wall 6. The rear wall 7 of the casinp carries a plate 8 having twtroutward y extending side arms'9', 9 in the outer or free ends cut awa to form bearin s and in which is gou'rnale a shaft 10, sai' shaft adjacent to the slotted from Upon the shaft at'the ends thereof are mounted wheels 11 and 19,

the wheel 12 being provided with teeth 14 to serve functionally asa ratchet wheel. The wheels are provided with a plurality of circ'umferehtislly arranged openings and in said openings are mounted a plurality of short rods or pins 16, said rods being suitably retained in engagement with said wheels. From the rods 16 are suspended it plurality of plate holders 17, each. holder comprising a channel U-shnped frame 13 carrying -pierced lugs 19, 19,10 receive the rod 16, and having a slotted end 20, wher 'hv plates 21 may be placed within the holders. The one side of each plate is provided with the name of a street, while the opposite side is provided with a suitable advertisement or notification. The rod. 16 are arranged sothat a portion of t e plate holder 17 will be suspended between the wheels 11 and modified form of com l2, while the remainder of the plate holders armature 23 carrying a springheld hookshaped arm 24. The arm 23 is pirotally connected to the end of a forwardly projecting arm 23" secured to the wall 7. The elec- ,5 tromagnets 22 are preferably located at the end of the box adjacent to the ratchet wheel 12 whereby the spring hold toothed arm 24 may normally engage the teeth 14 of the wheel 12. The plate 8 within the casing 53 is )rovided with binding posts 25 and 26 an these posts connect by wires 27 and 28 respectively with an electrical circuit which operates the street car 1, the wire 27 passing upwardly through the car and along the trolley pole 2, to an insulated contact arm 29 carried by the harp 30 of said pole, while the wire 28 is grounded, by connecting it to one 'of the axles of the car or like piece of mechanism. which will insure a positive cir-' cuit as will be presently described. 7

At. each street along the route of a our line, we rovide the trolley wire support 31 with a spending insulated a'rm 32 having a curvedspring contact block 33. The arm 32 is connected by a wire 34 with the trolley wire 3 and the o erationrof our improved indicator is as ollows:-As' the car up proaches a cross street,\th'e contact arm 29 carried by the trolley will engage the spring contact block 33 carried by the depending arm 32 of the trolley wire support, a a circuit willlbe completed through the trolley wire 3 to the source of electrical'enefgy A, through the ground B, wire 28 to the elecarm 29, which willenergizefifi fectromagnets 2 'ractthe jar-mature 23, and through the medium of the toothed arm 24 rotate the ratchet wheel 12, which will in the electroma ets'are actuated; The armature'23 is shifted clear of the cores of the magnets 22 when these'latter, are denergized b a spring 23? which is attached 'to the Will 7 and the tree endof the armature '23? s eac sign plate 2 1 is brou'ght 'to dis; play position to. expose the; name -of the street or station; it is engageda t itsuppew rude or pins so that "when the plate drops,, the reversed side thereof will be exposed.

the "p '2 and 5 of the drawin tromagnets 22; and throughwire 21m tlfiaturn. display thename of a street each time endli tll'tn in the presence of two witnesses.

throu h the 'opetling3' such reversed sideof lime inaylbe providedwith an advertisen'ient or any other inscription. The plates 21 may he readilifchanged in their holders by bringing cach holder around to the opening in the front wall of the casing, and holding the plates projecting out through the front wall, so that the plates may be withdrawn through the opening 20, the perforated lugs or hangers 19 being of snflicient length to permit of this operation.

in Fig. 10 of the drawings is shown a slight modification in a manner of mounting operator of a car can also be used, whereby when; a street or station is passed without stopping, and thetrolley contact should fail to operate, the motorman or operator of a car can easily close the indicator circuit, actuate the same and thus insure. a perfect operation of the indicator.

The present invention rcsides articularly in the construction illustrated in Figs. the remainder of the mechanism il ated in this-a lication being disclosed in the Letters fitmtt heretofore mentioned.

Such changes in the construction and'op eration of our improved indicator as are within theseo e of the appended claim, may be resort to without departing from the s irit and scope-of the invention.
